I have a EEG dataset that is channels x data point(16x62352) with 30 trials in it, how to is convert the matrix into a 3D one such that is (channels x data points x trials) which is (16x62352x30)?

I would try it using the reshape command, i.e. something like
reshape(EEG_orig,16,62352,30)
Possibly you need to transpose your original data or give the dimensions in a different order. If this is the case you might need something like shiftdim or permute to get the dimensions in the correct order afterwards.
